## Why TRELLO_GET_CARDS_CHECK_ITEM_STATES_BY_ID_CARD is rated Low

This tool queries and retrieves data about checklist item states on a Trello card. It performs a read-only operation with no side effects, no data modification, and no external execution. The limited scope (item states only, not full details) further reduces risk. Misuse would at worst expose minor task metadata, but cannot modify boards, cards, or user data, nor trigger financial or destructive actions.

From the tool's own definition: "Tool description states it 'Gets the states...of checklist items' and 'returns only item states' — a retrieval operation with no modification, deletion, or execution capability."

## Use case

AI agents call TRELLO_GET_CARDS_CHECK_ITEM_STATES_BY_ID_CARD to retrieve information from Trello without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
